This document covers recent software changes to the config file that
|
|
are not backwards compatible. It is a good idea to review this
|
|
document when upgrading the Klipper software.
|
|
|

# Changes
|
|
|
|
20200902: The RTD resistance-to-temperature calculation for MAX31865
|
|
converters has been corrected to not read low. If you are using such a
|
|
device, you should recalibrate your print temperature and PID settings.
|
|
|
|
20200816: The gcode macro `printer.gcode` object has been renamed to
|
|
`printer.gcode_move`. Several undocumented variables in
|
|
`printer.toolhead` and `printer.gcode` have been removed. See
|
|
docs/Command_Templates.md for a list of available template variables.
|
|
|
|
20200816: The gcode macro "action_" system has changed. Replace any
|
|
calls to `printer.gcode.action_emergency_stop()` with
|
|
`action_emergency_stop()`, `printer.gcode.action_respond_info()` with
|
|
`action_respond_info()`, and `printer.gcode.action_respond_error()`
|
|
with `action_raise_error()`.
|
|
|
|
20200809: The menu system has been rewritten. If the menu has been
|
|
customized then it will be necessary to update to the new
|
|
configuration. See config/example-menu.cfg for configuration details
|
|
and see klippy/extras/display/menu.cfg for examples.
|
|
|
|
20200731: The behavior of the `progress` attribute reported by
|
|
the `virtual_sdcard` printer object has changed. Progress is no
|
|
longer reset to 0 when a print is paused. It will now always report
|
|
progress based on the internal file position, or 0 if no file is
|
|
currently loaded.
|
|
|
|
20200725: The servo `enable` config parameter and the SET_SERVO
|
|
`ENABLE` parameter have been removed. Update any macros to use
|
|
`SET_SERVO SERVO=my_servo WIDTH=0` to disable a servo.
|
|
|
|
20200608: The LCD display support has changed the name of some
|
|
internal "glyphs". If a custom display layout was implemented it may
|
|
be necessary to update to the latest glyph names (see
|
|
klippy/extras/display/display.cfg for a list of available glyphs).
|
|
|
|
20200606: The pin names on linux mcu have changed. Pins now have names
|
|
of the form `gpiochip<chipid>/gpio<gpio>`. For gpiochip0 you can also
|
|
use a short `gpio<gpio>`. For example, what was previously referred
|
|
to as `P20` now becomes `gpio20` or `gpiochip0/gpio20`.
|
|
|
|
20200603: The default 16x4 LCD layout will no longer show the
|
|
estimated time remaining in a print. (Only the elapsed time will be
|
|
shown.) If the old behavior is desired one can customize the menu
|
|
display with that information (see the description of display_data in
|
|
config/example-extras.cfg for details).
|
|
|
|
20200531: The default USB vendor/product id is now 0x1d50/0x614e.
|
|
These new ids are reserved for Klipper (thanks to the openmoko
|
|
project). This change should not require any config changes, but the
|
|
new ids may appear in system logs.
|
|
|
|
20200524: The default value for the tmc5160 pwm_freq field is now zero
|
|
(instead of one).
|
|
|
|
20200425: The gcode_macro command template variable `printer.heater`
|
|
was renamed to `printer.heaters`.
|
|
|
|
20200313: The default lcd layout for multi-extruder printers with a
|
|
16x4 screen has changed. The single extruder screen layout is now the
|
|
default and it will show the currently active extruder. To use the
|
|
previous display layout set "display_group: _multiextruder_16x4" in
|
|
the [display] section of the printer.cfg file.
|
|
|
|
20200308: The default `__test` menu item was removed. If the config
|
|
file has a custom menu then be sure to remove all references to this
|
|
`__test` menu item.
|
|
|
|
20200308: The menu "deck" and "card" options were removed. To
|
|
customize the layout of an lcd screen use the new display_data config
|
|
sections (see config/example-extras.cfg for the details).
|
|
|
|
20200109: The bed_mesh module now references the probe's location
|
|
in for the mesh configuration. As such, some configuration options
|
|
have been renamed to more accurately reflect their intended
|
|
functionality. For rectangular beds, `min_point` and `max_point`
|
|
have been renamed to `mesh_min` and `mesh_max` respectively. For
|
|
round beds, `bed_radius` has been renamed to `mesh_radius`. A new
|
|
`mesh_origin` option has also been added for round beds. Note that
|
|
these changes are also incompatible with previously saved mesh profiles.
|
|
If an incompatible profile is detected it will be ignored and scheduled
|
|
for removal. The removal process can be completed by issuing the
|
|
SAVE_CONFIG command. The user will need to re-calibrate each profile.
|
|
|
|
20191218: The display config section no longer supports "lcd_type:
|
|
st7567". Use the "uc1701" display type instead - set "lcd_type:
|
|
uc1701" and change the "rs_pin: some_pin" to "rst_pin: some_pin". It
|
|
may also be necessary to add a "contrast: 60" config setting.
|
|
|
|
20191210: The builtin T0, T1, T2, ... commands have been removed. The
|
|
extruder activate_gcode and deactivate_gcode config options have been
|
|
removed. If these commands (and scripts) are needed then define
|
|
individual [gcode_macro T0] style macros that call the
|
|
ACTIVATE_EXTRUDER command. See the config/sample-idex.cfg and
|
|
sample-multi-extruder.cfg files for examples.
|
|
|
|
20191210: Support for the M206 command has been removed. Replace with
|
|
calls to SET_GCODE_OFFSET. If support for M206 is needed, add a
|
|
[gcode_macro M206] config section that calls SET_GCODE_OFFSET. (For
|
|
example "SET_GCODE_OFFSET Z=-{params.Z}".)
|
|
|
|
20191202: Support for the undocumented "S" parameter of the "G4"
|
|
command has been removed. Replace any occurrences of S with the
|
|
standard "P" parameter (the delay specified in milliseconds).
|
|
|
|
20191126: The USB names have changed on micro-controllers with native
|
|
USB support. They now use a unique chip id by default (where
|
|
available). If an "mcu" config section uses a "serial" setting that
|
|
starts with "/dev/serial/by-id/" then it may be necessary to update
|
|
the config. Run "ls /dev/serial/by-id/*" in an ssh terminal to
|
|
determine the new id.
|
|
|
|
20191121: The pressure_advance_lookahead_time parameter has been
|
|
removed. See example.cfg for alternate configuration settings.
|
|
|
|
20191112: The tmc stepper driver virtual enable capability is now
|
|
automatically enabled if the stepper does not have a dedicated stepper
|
|
enable pin. Remove references to tmcXXXX:virtual_enable from the
|
|
config. The ability to control multiple pins in the stepper
|
|
enable_pin config has been removed. If multiple pins are needed then
|
|
use a multi_pin config section.
|
|
|
|
20191107: The primary extruder config section must be specified as
|
|
"extruder" and may no longer be specified as "extruder0". Gcode
|
|
command templates that query the extruder status are now accessed via
|
|
"{printer.extruder}".
|
|
|
|
20191021: Klipper v0.8.0 released
|
|
|
|
20191003: The move_to_previous option in [safe_z_homing] now defaults
|
|
to False. (It was effectively False prior to 20190918.)
|
|
|
|
20190918: The zhop option in [safe_z_homing] is always re-applied
|
|
after Z axis homing completed. This might need users to update custom
|
|
scripts based on this module.
|
|
|
|
20190806: The SET_NEOPIXEL command has been renamed to SET_LED.
|
|
|
|
20190726: The mcp4728 digital-to-analog code has changed. The default
|
|
i2c_address is now 0x60 and the voltage reference is now relative to
|
|
the mcp4728's internal 2.048 volt reference.
|
|
|
|
20190710: The z_hop option was removed from the [firmware_retract]
|
|
config section. The z_hop support was incomplete and could cause
|
|
incorrect behavior with several common slicers.
|
|
|
|
20190710: The optional parameters of the PROBE_ACCURACY command have
|
|
changed. It may be necessary to update any macros or scripts that use
|
|
that command.
|
|
|
|
20190628: All configuration options have been removed from the
|
|
[skew_correction] section. Configuration for skew_correction
|
|
is now done via the SET_SKEW gcode. See skew_correction.md
|
|
for recommended usage.
|
|
|
|
20190607: The "variable_X" parameters of gcode_macro (along with the
|
|
VALUE parameter of SET_GCODE_VARIABLE) are now parsed as Python
|
|
literals. If a value needs to be assigned a string then wrap the value
|
|
in quotes so that it is evaluated as a string.
|
|
|
|
20190606: The "samples", "samples_result", and "sample_retract_dist"
|
|
config options have been moved to the "probe" config section. These
|
|
options are no longer supported in the "delta_calibrate", "bed_tilt",
|
|
"bed_mesh", "screws_tilt_adjust", "z_tilt", or "quad_gantry_level"
|
|
config sections.
|
|
|
|
20190528: The magic "status" variable in gcode_macro template
|
|
evaluation has been renamed to "printer".
|
|
|
|
20190520: The SET_GCODE_OFFSET command has changed; update any g-code
|
|
macros accordingly. The command will no longer apply the requested
|
|
offset to the next G1 command. The old behavior may be approximated by
|
|
using the new "MOVE=1" parameter.
|
|
|
|
20190404: The Python host software packages were updated. Users will
|
|
need to rerun the ~/klipper/scripts/install-octopi.sh script (or
|
|
otherwise upgrade the python dependencies if not using a standard
|
|
OctoPi installation).
|
|
|
|
20190404: The i2c_bus and spi_bus parameters (in various config
|
|
sections) now take a bus name instead of a number.
|
|
|
|
20190404: The sx1509 config parameters have changed. The 'address'
|
|
parameter is now 'i2c_address' and it must be specified as a decimal
|
|
number. Where 0x3E was previously used, specify 62.
|
|
|
|
20190328: The min_speed value in [temperature_fan] config
|
|
will now be respected and the fan will always run at this
|
|
speed or higher in PID mode.
|
|
|
|
20190322: The default value for "driver_HEND" in [tmc2660] config
|
|
sections was changed from 6 to 3. The "driver_VSENSE" field was
|
|
removed (it is now automatically calculated from run_current).
|
|
|
|
20190310: The [controller_fan] config section now always takes a name
|
|
(such as [controller_fan my_controller_fan]).
|
|
|
|
20190308: The "driver_BLANK_TIME_SELECT" field in [tmc2130] and
|
|
[tmc2208] config sections has been renamed to "driver_TBL".
|
|
|
|
20190308: The [tmc2660] config section has changed. A new
|
|
sense_resistor config parameter must now be provided. The meaning of
|
|
several of the driver_XXX parameters has changed.
|
|
|
|
20190228: Users of SPI or I2C on SAMD21 boards must now specify the
|
|
bus pins via a [samd_sercom] config section.
|
|
|
|
20190224: The bed_shape option has been removed from bed_mesh. The
|
|
radius option has been renamed to bed_radius. Users with round beds
|
|
should supply the bed_radius and round_probe_count options.
|
|
|
|
20190107: The i2c_address parameter in the mcp4451 config section
|
|
changed. This is a common setting on Smoothieboards. The new value is
|
|
half the old value (88 should be changed to 44, and 90 should be
|
|
changed to 45).
|
|
|
|
20181220: Klipper v0.7.0 released
|
